Definition

Noun: A neuroimaging technique that measures brain activity by detecting changes in blood flow. It is a specialized application of magnetic resonance imaging (MRI) that identifies which areas of the brain are active during specific tasks or at rest.

Usage

This term is used in medical, neuroscientific, and psychological contexts to describe the technology, the procedure, or the resulting images/data. - The research relied on functional magnetic resonance imaging to map cognitive processes. - Functional magnetic resonance imaging revealed increased activity in the prefrontal cortex.

Examples
